ATS-34 used to be "the" steel and had an enormous following among the various makers and manufacturers. Seeing as how its virtues lay more in the edge holding realm than in being as stain resistant as other stainless steels, it actually isn't a likely candidate for pure show knives, as there are steels which are far easier to work with and still stay gloriously shiny in just about any environment. Actually, Buck is somewhat unique in the amount of performance it pulls out of 420 stainless, as THAT tends to be a steel very popular with purely decorative knives. Granted, they use 420HC rather than 420J2.
